<span>The mass of potassium is 39. This is obtained by adding the 19 protons and 20 neutrons found inside the nucleus</span>
<u>Given that:</u>
height (h) = ?
mass (m) = 2 Kg ,
Potential energy (P.E.) = 100 J ;
We know that P.E = m × g × h
100 J = 2 × 9.81 × h
h = (100) ÷ (2 × 9.81)
<em> h = 5.09 m</em>
Answer:
B
Explanation:
Is the equilibrium stable or unstable for the third charge
Explanation:
The emf is equal to the work done on the charge per unit charge (ϵ=dWdq) when there is no current flowing. Since the unit for work is the joule and the unit for charge is the coulomb, the unit for emf is the volt (1V=1J/C).
You would gravitate towards Jupiter because if it’s large mass it has a stronger gravitational pull
